In response to Re: Noisy Drain Pipes
Replacing the plastic riser pipes with cast iron will reduce the sound considerably and then insulating around them should complete the sound proofing. The condensate lines should connect into the side of a sink tailpiece so that the condensate will quietly run down the inside of the pipe. If there is a build up at its exit into the pipe, or if the connection is made into the top of a horizontal line, then the water will drip into the water in the trap and make a noise.
: New two story house. When any of the upstairs toilets or showers etc. are running you can hear (downstairs) the water running down the drain pipes. When the toilets flush it sounds like it is all dropping on your head. What can we do to muffle or eliminate the noise. If needed I am willing to bear the expense of opening up the walls to insulate, wrap, foam, etc.

: The next problem is the air condtioner condensation line drip noise coming out of the sinks that are commonly hooked into the same drain. Code requires the a/c line to be hooked into the drain. All a/c units are in the attic off the second story and the sound coming from the sinks downstairs is loud.
